|dc.description.abstract||THE NATIONAL PARK. This Park, the largest in the workd, area 3578 sq, miles, elevation above the sea from 6000 to 14,000 ft., is on both sides (but mainly on E. side) of the main range of the Rocky Mts., in N. W. corner of Wyoming Territory, U.S. of A. It was made a National Park by Act of Congress, approved March 1, 1872, and contains a far greater number and variety of natural wonders lakes, cataracts, canons, mud volcanos, solfataras, fumaroles, ornamental hot springs, spouting geysers, etc., than any other equal area on the globe. The Periodical Hot Lake is one of the White Mt. Mammoth Hot Springs (see views from Nos. 89 to 109 inclusive) on Gardiner's River (see Nos. 79 to 88 inclusive). It is dry for a few weeks in summer; and the first four views show the general appearance of its empty crater from different points, while the last three views show how the calcic carbonate, carried in solution by its hot waters, is deposited in marvellously accurate imitations of leaf forms. None of the Mammoth Hot Springs are now active geysers, the principal geysers of the Park being located on the Fire Hole Fork of the Madison Branch of the Missouri River, and on the Shoshone Fork of the Snake River. For Geyser Views, see Nos. 7 to 44 inclusive, of which Nos. 9, 14, 19, 20, 24, 25, 34, 36, 37, 38, 39, 40, and 41 are beautiful views of geyser craters; and Nos. 10, 11, 12, 13, 15, 35, 41, and 42 are fine photographs of great geysers in eruption. For scenes in the Valley of the Yellowstone River, see Nos. 51 to 78, and 117 to 121, inclusive. For Madison and Fire Hole Views, see Nos. 1 to 6, and 45 to 50, inclusive.
